CONTROLLING DEVICE FOR TRACTION-VEHICLES...

To all whom it may concern:

Be it known that I, LESLIE S. HACKNEY, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented new and useful Improvements in Controlling Devices for Traction-Vehicles, of which the following is a specification.

The common forms of traction vehicles ordinarily employ a number of controlling devices located and operated so as to necessitate the constant presence of the operator on the vehicle and when such tractors are used to supply motive power for earth-working and other like machines, a second attendant is required to manipulate the operating mechanism of such machine.

It is my object to "provide a controlling device for a traction vehicle adapted to steer the same, regulate the operation of its engine and actuate its power transmitting mechanism through a flexible extension are ranged to be manipulated from the machine or trailer drawn by said traction vehicle.

In other words, I propose to control both the tractor and the hauled implement from a single position on the latter. In the drawings, Figure 1 is a side elevation of my improved device; Figs. 2, 3, a and 5 arerespectively detail views illustrating certain parts thereof.

Referring to the drawings, I have used the reference numeral 10 to indicate the ing rigidl secured thereto. A steering shaft 15, sli ably and revolubly supported within said bearing, is operatively connected in any convenient manner (not shown) with the steering devices and transmission gearing of the tractor whereby the same are respectively operated when said shaft is turned and moved longitudinally. A lever quadrant 16, having a notched are 17 thereon, is formed upon the bearing 14. Actuating levers 18 and 19, pivoted upon the quadrant 16, frictionally engage the opposite sides of the notched are 17 and said'levers are connected with actuating rods 2Q and 21 passing to the engine (not shown) of the tractor.

Specification of Letters Patent.

I drawings.

The post 13 is secured to the frame 11 of "the implement and the bearing 22, having a guide 23 thereon, is pivoted vertically and swiveled horizontally upon said post. The steering shaft 15 is slidably and revolubly mounted, in the bearing 22. Said shaft is supplied at the rear end thereof with a hand rearward nearly to the hand wheel 24 and pass through openings 26 in the guide 23.

To facilitate applying my improved mechanism to machines of various styles and sizes, I make each of the rods 20 and 21 and the shaft 15" in two parts, said parts being telescopicall joined and secured in adjustable relation y means of a pin 15 or the like, as illustrated in detail in Fig. 4 of the The connection between the 0st 13 and bearin 22 is formed by a lin 29. Said link pivotally supports the hearing at its upper end, and is supplied with anannular flange 30 at its lower end which is retained, free to turn, in the annular groove 31 in the top of said post.

In use, the operatorsits upon the implement and manipulates the wheel 24 and actuating rods 20* and 21 to control the tractor, the steeringshaft 15, and said rods 20 and 21 being automatically adjusted to accommodate themselves to varying relative positions of the tractor and implement.

Having described my invention, what I claim as new and desire to protect by Letters Patent, is:

1. The combination with a tractor and a vehicle flexibly attached thereto, .of a support upon said tractor, a second 'su port upon said vehicle, a mounting pivoted vertically and horizontally upon said last-mentioned'support, and an operating shaft having a hand wheel thereon, said shaft being carried by said mounting and said firstmentioned support.

75 turned end of the rod. These rods extend 2. The combination with a tractor and a vehicle flexibly attached thereto, of a flexible and extensible operating device carried by said tractor and vehicle and adapted to control the former from a position upon the latter and also to compensate for the irregularity of movement in travel between said tractor and vehicle, said device including a steering shaft and actuating rods, which consist of members telescopically joined and secured in adjustable relation.

3. The combination with a tractor and a vehicle flexibly attached thereto, of a support upon said tractor, a second support upon said vehicle, a mounting pivoted vertically and horizontally upon said last mentioned support, a shaft having a hand wheel thereon, said shaft being revoluble and slidable in said mounting and in said first mentioned support and being also formed With a flexible joint between said mounting and support, and actuating rods for the tractor mechanism slidable in said mounting.

teatime 4:. The combination with a tractor and a machine flexibly attached thereto, of a suport u on said tractor a second suo ort 7 A.

uponsaid vehicle, a mounting pivoted vertically and horizontally upon said last mentioned support,a shaft having a hand wheel thereon, said shaft being revoluble and slidable in said mounting and in said first mentioned support and being also formed With a flexible joint between said mounting and support, and actuating rods for the tractor mechanism slidable in said mounting, said rods and shaft comprising members telescopically joined and secured in adjustable relation.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
